Halfway Between 11 and 319

When you ask "What number is halfway between 11 and 319?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=319.

Halfway Between Line

To find the number halfway between 11 and 319, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 319 into our formula, we get:

(11 + 319)/2 = 165

Thus, the number halfway between 11 and 319 is 165.

To check that our answer is correct, we subtract 11 from 165 and subtract 165 from 319 and compare the two numbers:

165 - 11 = 154
319 - 165 = 154

As you can see, the halfway number is 154 higher than 11 and 154 lower than 319. Therefore, our halfway between answer of 165 above is correct.
